chooseGCM: an R package with a toolkit to select General Circulation Models

chooseGCM chooseGCM website

The goal of chooseGCM is to help researchers aiming to project Species Distribution Models and Ecological Niche Models to future scenarios by applying a selection routine to the General Circulation Models.

Installation

You can install the development version of chooseGCM from GitHub with:

install.packages("devtools")
devtools::install_github("luizesser/chooseGCM")

The package is also available on CRAN. Users are able to install it using the following code:

install.packages("chooseGCM")

Other packages

If you liked chooseGCM, get to know our other packages. Currently, we have also the caretSDM package, a package to run Species Distribution Modeling, which is also used in the article

to test chooseGCM using SDMs.

Three breakthroughs distinguish caretSDM:

  1. The strong geoprocessing background that allows for automation on spatial data handling by rescaling data to a common grid, with the possibility to model distributions using river networks (via segmented lines), overcoming limitations for aquatic species, while also enabling interactive data viewing without the use of an external GIS software;

  2. The underlying ML tools that allows for the integration of 115+ classification algorithms with automated workflows, from hyperparameter tuning to ensemble prediction, eliminating coding barriers for advanced techniques, while allowing flexibility for experienced users;

  3. The use of recyclable objects, designed to track all analysis steps within a single class, enhancing transparency and scientific rigor.

caretSDM is available on both GitHub and CRAN:

install.packages("devtools")
devtools::install_github("luizesser/caretSDM")
install.packages("caretSDM")

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
